Yeast Two-Hybrid Essay -- Biology, DNA

The initial transformation task required two yeast strains (both as Mav203; Leu–, Trp–, His–), with one containing the pDBLeuDa4 bait plasmid, and the other with just the pDBLeu plasmid. The two strains were each transformed with a pPC86DMID1(Y) prey plasmid, where (Y) referred to a full-length positive control (MID1) , a DBB strain (MID1DBB), and a DCC strain (MID1DCC). The transformation process with the two strains and three prey plasmid DNAs resulted in 6 (2x3) transformation mixtures (Table 1). The transformation mixtures were then spread-plated at 1x and 1/10x dilutions using half of each plate on an SC (synthetic complete) yeast growth medium minus selected amino acid(s); one plate without Leucine (SC-Leu), and two plates without Leucine and Tryptophan (SC-Leu-Trp). Plates were then incubated for 4 days at 30 ° C, however due to failed growth in the transformation plates for pPC86DMID1 (both yeast strains), and an additional set of results had to be obtained. The spread-plated results for each strain, transformation, result source, and their associated control cases can be seen in Table 2, with a â€Å"Yes† growth observation referring to confluent growth and â€Å"No† for non-confluent growth. Following the incubation period, each of the 6 transformation plates were sampled and underwent 4x 10-fold serial dilutions, which were then spot-tested to either an SC-Leu-Trp, or SC-Leu-Trp-His (minus Histidine) medium. Each strain-transformation occupied half of each plate, with a spot per dilution level (Figure 1). An additional set of spot-tests were also performed to test for auto-activation of the a4 bait protein, using a strain transformed with an unmodified pPC86 plasmid (MaV203+pDBLeuDa4+pPC86). Following another round of in... ...the DCC variant (for all spot dilution levels). The lack of growth for the DBB variant suggested the B-box region was a requirement for interaction/binding with the a4 protein, while the coiled-coil domain didn’t appear to be a requirement. Its removal however did result in noticeably decreased growth rates when compared to the full-length control test, suggesting its removed resulted in some level of decreased interaction with a4, whether it usually stabilised the binding process, or is removal disrupted the overall form and binding site is unknown, and would require additional testing. However given the external result source, it could have been that group’s sampling and dilution methods had resulted in decreased cell viability, though a simple retest could rule this out, and would be a good starting point to determine any interactions with the coiled-coil domain.

Hamlet’s Infatuation with Death

†An Undiscover’d Country†: Hamlet’s Infatuation With Death Have you ever wondered what happens to you when you kick the bucket? Will you still be the same person? Or is death really the great equalizer? Is it possible we all end up the same? Death is a very scary and lonely thing to think about, and nothing is a greater example of that than William Shakespeare’s famous play Hamlet. Hamlet is infatuated with the idea of death and what it brings. With comments like, â€Å"To die: to sleep; / No more,† (Hamlet 3. 1. 61-62) and â€Å"we fat all/ Creatures else to fat us† (4. 3. 3-24), it is clear Hamlet has a very lonely and depressing view on what happens when you bite the dust. Hamlet’s fascination with death and dismal view on it are all evident throughout the whole play. We start to learn that Hamlet has a bizarre fascination with death when, every other scene, he is talking how everyone will end up in the ground one way or anothe r. â€Å"To be or not to be – that is the question† (3. 1. 57), is where it all starts off. From this famous speech to the end of the play, all Hamlet worries about is death. He continues to go on and on about how we will all become equal and starts to wonder what it is like to die. Hamlet often talks about self-murder, or suicide, and how it will affect his afterlife if he decided to do it. HAMLET. O, that this too solid flesh would melt Thaw, and resolve itself into a dew! Or that the Everlasting had not fix’d His canon ‘gainst self-slaughter! O God! O God! (1. 2. 129-132) Hamlet is obviously contemplating suicide here, but then he realized that he cannot go to Heaven if he commits suicide. Going to Hell is something that Hamlet does not want at all. This is obvious because, throughout the play, Hamlet thinks about killing himself, but he never does because he is scared to die, and even worse, scared to go to Hell. The language that Hamlet uses to express death is very interesting. The way and how Hamlet talks about death all the time is extremely depressing to read and I can only imagine how it made Hamlet depressed. Hamlet often has trouble with expressing his views on death as he often has conflicting statements. Sometimes he will think of death as an adventure, â€Å"The undiscover’d country from whose bourn/ No traveller returns† (3. 1. 81-82), or he will think of it as an extremely gruesome thing, â€Å"A certain/ Convocation of politic worms are e’en at him. † (4. 3. 21-22). The way he talks about death here is cringe-worthy. Just thinking about worms chowing down on Polonius is nauseating. Hamlet does not often talk about death this way in the play, though. He is almost making a joke in this quote, but the joke is true and extremely gross. Hamlet’s view on death is very dark and grim. His believe that death makes us all equal and there is nothing we can do to prevent that. In Act Five, Hamlet is in a graveyard with Horatio and is carrying on a very dark conversation with him. Hamlet has a very interesting quote in this Act, â€Å"Alexander died, Alexander was buried, / Alexander returneth into dust† (5. 1. 189-190). This quote is about Alexander the Great, and his name should go without saying that he was a very important person. It is depressing to think about it because Alexander was a great king. But he ended up like we will all end up, and that is dust in the ground. In the same scene Hamlet drops another interesting quote, â€Å"let her paint an/ Inch thick, to this favor she must come† (5. 1. 170-171). Hamlet happens to be holding the skull of Yorick when he says this. No matter how much make-up, or paint, you put on, no matter how much you dress up and act fancy, you will still end up like Yorick. And the sad part is that there is nothing you can do to prevent it. Mortality is a very commonly thought about in this play. Hamlet is not the only character that worries about the afterlife. Almost every character in the play has a view on life and death. Their views maybe different, most are still depressing. This theme is present because Shakespeare’s view on death was depressing. Hamlet’s view on death is a direct relation to William Shakespeare’s. They both believe we will end up the same; a dead body in the ground.

19th Century America Essay

Social Studies Essay Throughout the 19th century, America was a rapidly growing country. It was full of new inventions, new ideas, economic and social development, and new ways of thinking. But, most of these came from the North. The North and the South had many differences and many similarities. The North and South had many differences. One difference is that South’s economy relied on slaves more than the North. Almost all the Northern states immediately or gradually abolished slavery after the Revolutionary War. Another economic difference is that the South’s economy was based on â€Å"cash crops†. â€Å"Cash crops† include rice, tobacco, indigo, and cotton. The South had many plantations to support its farming economy. The North had many small farms as well as larger towns and cities. The North relied more on factory work. In the North, railroads and canals connected the states, allowing for greater economic development. The South’s social development was also very much different from the North’s. For example, in the South, the wealthy plantation owners and the slave owners were at the top. They supported their plantations with slavery. In the North, the upper class was made up of mostly city people who owned factories. Many of the factory workers were European immigrants. One example of a similarity is the class structure. They both had a very small upper class, a small middle class, and a large lower class. Another example is that the white men had all the power, and slaves and women didn’t have equal rights with the white men. In terms of economic similarities, farming was an important part of the economy in both the North and the South. These two regions obviously had many differences. In many ways, this strengthened the nation. The North’s factories processed the South’s crops, which tied the nation together. Also, having male dominance and having women and African Americans with no equal rights kept the nation together. But, these differences also created conflicts, which threatened the nation. The North wanted to abolish slavery for good, but the South needed slavery for crops, such as cotton. Because of this conflict, the Civil War would start later on. Overall, both regions’ differences threatened the nation. When the cotton gin was invented, this caused further conflict. It gave the South more reasons to keep slavery. Another conflict was the difference in wealth between the North and the South. The North had a more developed economy with canals, railroads, and factories. The South continued to rely on agriculture as its main component of the economy, requiring them to import manufactured goods. In conclusion, the North and the South were, overall, very different, but with some similarities. These differences strengthened the nation in a few ways and threatened the nation in many ways. The differences in social and economic structure led to the Civil War.

5 Ways to Make Your Resume Stand Out

5 Ways to Make Your Resume Stand Out Human Resources Associates, Recruitment Agents, and Hiring Managers are bombarded daily with resumes. Realistically they do not have the time to scour through every single resume reading about your special talent, or your favorite hobby. Because of the limited amount of time these professionals have they are always on the lookout for ways to weed out candidates rather quickly. Shockingly, some hiring managers can simply give a single glance to a resume and decide whether it’s a ‘yes’ or ‘no’. So, it is very important that you make those few seconds count, and possibly land in the forefront of thousands of competing candidates. Here are five ways to take your resume to the next level. Make sure that your resume is rid of any errors and that the readability is simple and easy. Making the decision to use an artsy resume template or something exorbitant is the first door to easy rejection. Remember less is always more and simple triumphs every time. Most often, reps equate typos and errors with laziness and the last impression you want to convey is laziness. Use your resume to tell your story. Your resume is a snapshot of your dependability, work ethic, work patterns, etc. Control the narrative and make the story count. You can do this by displaying your professional experience, accomplishments, skills, talents, and relevant knowledge for the job you are applying to. The trick is to make it long enough to tell your story through growth, promotions, and advancements. But once again you want to make it short enough to be able to obtain the information in one glance. THE COVER LETTER IS NOT OPTIONAL. A cover letter is a auxiliary tool for the resume, while many of us think it is useless and optional it could really be the deciding factor behind whether you advance to the next step or not. Unless the hiring manager explicitly says to ignore the cover letter then take the time to write and customize one. Include enough buzzwords and keywords pertaining to your intended industry. Buzzwords are meant to describe your capabilities and demonstrate how you are a better fit for the position. Some examples include budgeted, compiled, facilitated, merchandised, resolved, or upgraded. But be careful to not include some of the overused buzzwords such as, specialized, leadership, excellent, creative, or experienced. Use a header. The header will be the first thing that a hiring manager may see and it’s a statement that should typically be in caps presenting important information rather quickly

Population growth and the degradation of the environment Essay

Population growth and the degradation of the environment - Essay Example In our case this is because the relationship between human population growth and wildlife extinctions is not always direct. We are a species with an insatiable appetite for resources, and we sometimes use them irresponsibly. Thus, it could be argued, what we do and how we survive may be more important to our impact on other species than the simple effect of our great numbers. Thus we need solid evidence to establish that, over the broad sweep of time, there is a close tie between the simple count of people on the planet and the diminishing count of other species. In other words, the impact of our large population would be great even if we were to behave differently. If there is such a link, then it is particularly frightening, for there are now over six billion people on the planet. Nature has been "comparatively sparing" in the space and resources necessary to support both wildlife and a human population. Malthus was the economist who warned us in 1798 that the human population would grow more quickly than the resources necessary to sustain it. Now I know that Malthus and his ideas have been much maligned over the years by optimists who see no problem with human population growth. Thus in 1998, the two hundredth anniversary of his publication went almost without notice. The following year, the milestone number of A.D. 2000 got much more press than another milestone number: six billion, the number the human population reached sometime midway through the year. Granted, both are arbitrary numbers. But to a few of us concerned scientists, the population milestone was far more frightening than the computer glitches predicted for "Y2K." Y2K had almost no effect; the six billion figure has a lasting and growing impact. Yet few people noticed the milestone, and even f ewer cared. Human population growth is outstripping resources, especially as it relates to the sustainability of earth's biodiversity. As Ohio novelist and conservationist Louis Bromfield put it in 1947, "The bitter truth is that we are having our noses rubbed in Malthusian theory." It is even truer today than it was then, for our population Human population growth is outstripping resources, especially as it relates to the sustainability of earth's biodiversity. As Ohio novelist and conservationist Louis Bromfield put it in 1947, "The bitter truth is that we are having our noses rubbed in Malthusian theory". It is even truer today than it was then, for our population size has since doubled. Many of the world's population live in poor countries already strained by food insecurity; inadequate sanitation, water supplies and housing; and an inability to meet the basic needs of the current population. These same countries are also among the fastest growing places in the world. A large proportion of these populations are supported through subsistence agriculture. As populations grow, competition for fertile land and the use of limited resources increases. The people living in these countries are also moving toward a greater standard of living, perhaps matching the lifestyles of the more developed countries whose current consumption patterns and resource use are not necessarily sustainable. Quite simply, if we want to conserve biodiversity on earth, the most important conservation measure we can take is to slow or halt the growth of the human population. Frankly, a reduction in numbers from six billion may even be desirable. Now

Critically assess the potential use of the marketing information Essay

Critically assess the potential use of the marketing information system (MIS) to help marketing managers understand and fulfill - Essay Example However the previous research studies suggest that following avenues of the firms’ decisions in relation to its market operations are typically addressed in modern-day MIS; (1) the background factors (2) the actual information processing behavior and (3) the role of information activities in shaping the firm’s competitive advantage. Therefore it is clear that MIS address all the avenues of decision making in marketing. Current study attempts to compile the characteristics of the information processing involved in making sound marketing decisions and the specific advantageous of using MIS. Steps involved in information processing which is aimed at formulating sound marketing decisions are illustrated and the performances of modern-day MIS are evaluated in terms of the advantageous and scope for development. Marketing is a well structured subject area which contains clear conceptual frameworks and a substantial amount of empirical case studies which utilize the subject th eory. It is defined as â€Å"a social and managerial process whereby individuals and groups obtain what they need and want through creating and exchanging products and value with others† (Kotler, and Armstrong, 2010). ... changes in market conditions and anticipating market competition from new domestic and international firms entering into market and intensifying competition from the existing firms (3) design reliable marketing plans, considering the advantages and disadvantages of alternatives marketing strategies (4) find effective solutions to specific problems such as what is the best approach for launching a new product and what are the suitable product promotion strategies and (5) improve the overall performance of the organization by better controlling, monitoring and implementing marketing strategies which in turn increase the efficiency and the effectiveness of firms’ marketing division (Churchill, 2001; & Leonidou, and Theodosiou, 2004). Basic characteristics of MIS 1) The Background Factors Incorporated in MIS The background factors which can influence the marketing decisions include characteristics of the firm and the manager, government policies and consumer preferences and income levels. Previous researches which are aimed at exploring the background factors indicate that organizations with innovative cultures are more likely to seek information and appreciate its usefulness in making marketing decisions. Experience, level of education, cognitive styles and decision-making levels determine the manager’s information-processing style. Organizations which are not hierarchical in structure and decision making process is rather decentralized obtain more advantageous from MIS compared to those organizations which are highly formalized (Menon & Varadarajan, 1992). Moreover, the volatility in the external marketing environment also increases the degree of usefulness of MIS to marketing managers. Market volatility increases the supply and demand uncertainty which in turn

Discussion Board Post Response - Essay Example In my organization, nurses are able to get feedback on the quality of their services from their patients as well as from the general public through a facebook page created by the organization and also through twitter. This has greatly improved provision of services in my organization as weak points are easily identified and appropriate strategies implemented. I agree with your implication Hope Barham that the situation in your case scenario can be addressed through the nurse manager providing scheduling examples previously made and that have been a success and openly discussing them. In my opinion, social sites could play a vital role in improving the staff morale in your case scenario. Hader (2009) posits that social sites within a department can be used to "Share information, dialogue, and receive feedback and input from others" (p. 6). Therefore, you could allow the nurses to give their input through social sites and then incorporate their opinions and views in creating the schedules. Engaging the nurses in creating their schedules will enable them feel that their input is valued and hence feel motivated. Bestowing a schedule to employees that they have not been involved in creating is likely to be met with
